As a long time Software Engineer who moved into a DevOps Engineer role and now into an SRE role , Nana explained the differences of a DevOps Engineer and SRE very well. Good job!
Thank you Nana - After watching your videos as a software engineer for over two years I have just been offered my first job as a DevOps engineer at a startup. Many thanks!
I have worked both as a DevOps and SRE. Your explanation to both concepts and roles is on point. I personally prefer the DevOps role and I will be transitioning back to it. I enjoy more working in the Infrastructure as Code side, involved with CI/CD and Cloud tools. My Experience as an SRE was more related to monitoring and incident handling, which is sometimes a pain in the a**. Greetings from Colombia!
Great video! As an SRE at a big tech company, we do things a bit different than the well-known SRE concept mentioned in this video. We have dedicated tools teams filled with SWEs working on building the entire CI/CD platform and on-prem resource allocation. We also have dedicated netops, sysops teams working on networks, hosts, file-systems, etc. For SREs, we do the typical work like monitoring, oncall, automate dashboard generation, but the real fun stuffs are building technologies that help make the site more reliable and fast. Some examples are, we built our own monitoring platform, end-device availability observations, ML-powered incident triaging/mitigating, ML-powered service performance tuning, database data integrity detection/restoration, etc. All of the projects mentioned above help make the site more reliable but not necessary focusing on making feature delivery fast.
As an ex SRE and now DevOps engineer and in my opinion, no one really care what is the difference. I know only one company where the tasks of SRE and DevOps are different. For companies which are just steped into cloud computing (and not only those) both the DevOps and SRE are the fency words and describes the same System Administrator, who takes care about the infrastructure, able to solve their problems and restart appropriate service in the middle of the night. Why I'm writing this? Just to ask you, please, next time when you will get a message on Linkedin from recruiter who will say "hay, we have a cool DevOps position where you will need to be on-call and do some monitoring tasks" say him/her "but this is not a DevOps role. It sounds more SRE".
As a SRE we are setting, 1. we will collect metrics of different servers and displaying on Grafana dashboard ,2. operational alerts to respective teams. 3. ONCALL on P1/P2 incidents. 4. Submitting the RCA to clients 5. working on the Incident action items with the developement teams.
Good video. I think what you explained as SLA is actually SLO. SLA is more of a commercial agreement that specifies kind of fine when you fail to meet SLO. You also missed one very important topic which is SLI.
Great video. We're currently in the process of budding off from the platform engineering team (I still can't bring myself to say DevOps team) to start a dedicated SRE function. This video illustrates so much the direction I want to take the team, but with some differences as we're currently a very small team servicing a large number of developers. So taking a more horizontal / consultancy type approach. So some challenges there... But I am definitely going to share this video as it really gives a great introduction into much of what we want to achieve. Thank you.
Hello Nana! Great Video as always. I owe my entire DevOps Journey to you. From becoming a complete Noob to now Working Full Time as a DevOps Engineer, You are my saviour. I'm now trying to transition to SRE. Can you help me understand what Tools should I learn for this? Also a Zero to Hero on SRE would be absolutely wonderful ! Anyways Thanks for Everything !!!
As an SRE I like building and setting up the tools. For example writing scripts that detect changes and alert based on those incidents. But actually handling those incident is a pain in the ass because it involves a lot of communication with other people, emails etc
I'm a second year computer science student and this is the very first time I've ever heard of such a role named site reliability engineer. I guess there's still a lot to learn. Great video though❤❤
You have such a great way of explaining concepts like this. I've worked as a "DevOps" since 2003 - back then I was just a "build manager" and more recently am SRE at a big retailer. I don't think I really thought there was a difference and I'm not sure where I work that they think this way. You asked what would be great courses or videos - I'd love to hear more about infrastructure as code, configuration as code and best practices with tools like Terraform, Ansible, Chef/Puppet, Morpheus or even Jenkins/GitLab to run these "playbooks"
i think something missing here is the concept of "reducing toil." SRE have a lot of manual tasks. The team should look towards automation through both tooling and creating new applications that can do activities for SRE team.
Super informative as always nana. - thank you i take away a few things from this and probably wrong: 1. Job postings i look at, seem to get DevOps and SRE confused or at least blend the two together it would seem...judging by the tool set/overall goals the two disciplines aim for... 2. Wouldn't surprise me if in the future, smaller companies start demanding more and blend both DevOps and SRE discipline together to save money (given that there is some overlap in concepts/goals): DRE (Development Reliability Engineer) or SRO (Site Reliability Operative/tions) :)
The last segment is the best. I've been an SRE for 6 years or so now and never really noticed that we flip-flopped "personalities". In the 200X's ops wanted to slow the releases, congrol changes, etc. to keep things stable, while developers wanted to crank out chnages quickly with no care to stability. Fast forward to today and we've flipped. Now, the SRE (developers) want to focus on reliability while DevOps (Ops) want to crank up the speed of releases.
Good explanation however I would like to address your story about SLA & Error budget. SLA is an agreement as you explained, but you mention it's set by the business owner and engineering, typically that won't be the case. After breaching an SLA there is most of the time in the contract a line that would allow the customer some form of reimbursement (money back, opting out of the contract). Most of the story telling is actually about SLO's, which are objectives that are set by the people who own the service (from Product manager, Product Owner and engineering team). This is where the story of Error Budget makes much more sense. You will never go close to your SLA because that would put a high risk of reimbursement. In short and SLO might have the same metrics as an SLA however a SLO should always aim higher then an SLO, because then you are (as you mention) allowed to take risks from your error budget. But also you might have SLO's (let's let latency) that are at the start not an SLA, but after a period you can confidently add that latency as an extra agreement with your customers without making assumptions. This is where the power of history data comes in play. SLO/SLI and Error budgets require it's own video, it's so powerful if you connect the dots, it's for me key metrics that can be understood by everyone in the organisation.
Hey Lee, thanks for sharing with great details! I agree that this topic requires its own video, I didn't want to explain all the details in this SRE overview video
@@TechWorldwithNana I believe you touched on the important items and made it clear what the differences were so kudos for again explaining to a broader audience. Also agree with your point, SRE can go pretty broad in topics. I am btw (because you asked in your video) a SRE Lead/Manager.
Thanks Lee for your feedback and for sharing your valuable knowledge as an SRE lead here in the comments with others as well. There is definitely a need for more information on these topics in the community.
Hey NANA Loved the video as always. Just one suggestion, whenever your add started please add promotion alert or their logo in your video, it will help to differentiate the add and your content. In current loft promotion, after 10sec it feels it has ended but still it was going on.
bhaiji aapke jaise logon ki vajah se hi hum indians ki beijatti hoti hai. Har sponser chaahta hai k uske ad ko viewer neglect na ker paaye and that is what she is trying to do or aap us per lecture de rahe ho.
I thought SRE was a made up role when I was offered the position at my company. Whew, little did I know. I'm 2 months into it and this little software dev / software QA automator is swimming in a firehose of education. So much new to learn.
So, to summarize, in the past we had two teams with different objectives: Devs for speed, Ops for reliability. And now we have 2 teams with "different" objectives: SRE for reliability and observability and DevOps for speed in releases and infra provisioning. Nice 🙂👍
I don't agree with that statement. SRE cares about reliability and observability, they can be either included in teams or act as a consultant to the different teams. They mainly drive improvements forward and will help the teams achieve that next level on topics like reliability/scalability/performance/observability. In regards to your DevOps team, in a "you build it you run it" way, the teams will take the tasks of deployment and infra provisioning on themselves because they have all the know-how of the application. Unfortunately in many bigger/older companies, this is not true and you have siloed teams (dev/infra/qa...). Note: I don't like the term DevOps team, it's a philosophy and not a role.
@@azzy6543 For me that's indeed a platform team, not SRE. However many teams in the organisation can help and mature reliability within their team without being called SRE. However I would not consider the platform team to be true SRE's as they might have not enough influence on the application code itself.
I recently transitioned from an information systems engineer to an SRE. Our current company’s goal for this role is to create a CI/CD pipeline, since it does not exist yet. However, we want to be able to monitor and keep our systems up and reliable moving forward.
One of the best thorough and comprehensive explanations of SRE, or I must say, THE BEST! I love the comparison part between SRE and DevOps so much! Thank you for your work and knowledge, Nana!!
When you explain SLA you are really talking about SLO. The SLA is an agreement with some kind of consequences, usually financial. SLO is the objective that defines the availability, as an example, and the SLIs are the indicators you measure it with.
Overall, a good video. However, your explanation of SRE's role is around logging, monitoring and alerting. I thought I heard you say SRE's role is also to ensure what impacts new changes will have on the reliable and that this is through automation. And that this enables developers to push code more frequently. Other than the mention, I didnt hear how SRE does that. Specifically what are they automating to ensure new changes wont affect the site reliability. Is there more to an SRE other than logging, monitoring, alerting and post mortem?
interesting to see the difference between practical devops and sre. we have a team of devops engineers, but you can see who acts more according to the sre or practical devops roles.
Thank you very much for this Video. I am looking for a serious game introducing SRE. Do you have any ideas, tips, examples or links ? Thank you in advance
Very well explained.... I had a few gaps in understanding how SRE is different from DevOps ... your video covered all those gaps ... thanks a lot Nana for the wonderful explanation !!!!!
Without operations teams and incident management teams, who calculates the downtime or degradation of service accurately ? How do you keep track of the outages and lessons learned? Are the SRE expected to be incident managers as well? How does this operating model work with company that had numerous, critical 24/7 services or services that have very little appetite for downtime?
Great videos! Also watched the DevOps one, I especially appreciate how you address the ambiguities. My 2 cents on DevOps and SRE: are they almost the new Dev & Ops, but an upgraded version where both sides now need to have a broader knowledge of the full software life cycle. At the end of the day, each side still have their priorities (speed or reliability) as you can't really ask people to care about everything.
IT is really broken nowadays. Every few years new roles are introduced, but in the end the overall quality goes down or at least all projects proceed slower and slower. I remember times, when we handled projects in teams of 5 people in total (from project management, developers to operations at customer).

Can you please advise on the technologies to learn for a SRE role?
When you explain SLA you are really talking about SLO. The SLA is an agreement with some kind of consequences, usually financial. SLO is the objective that defines the availability, as an example, and the SLIs are the indicators you measure it with.
Thank you. Great video.
Thanks for the awesome video.Love the visualization and presentation❤️

Thanks Jayanth, happy you like the visuals :D

I remember times, when we handled projects in teams of 5 people in total (from project management, developers to operations at customer).
Nana...you are the best...!!!!
What tools would you say are the most important for SRE?
A scripting language, Docker and Kubernetes?
You are great Inspiration
